What is skew correction in image processing. This skew of the image(s) often makes us uncomfortable to visualize the text in the image and even when we use such skewed text image with optical character reader, as it degrades the resulting accuracy The python file contains a skew corrector for rectangle-like objects. We’ll start by creating a simple dataset that we can use to evaluate our text skew corrector. Sep 16, 2019 · The idea is to rotate the image at various angles and generate a histogram of pixels for each iteration. I have used the skew corrector on two types images Type 1: smooth with no interfering background Type 2: highly textured but more realistic image Mar 27, 2025 · Introduction: In digital document processing, skew correction is crucial for enhancing Optical Character Recognition (OCR) accuracy and information retrieval from scanned documents. Sample image and an oblique projection. . As we scan the text images using digital photography devices like cameras, scanners etc. Feb 21, 2024 · Image Skew Correction Skew correction in image processing, also known as deskewing, is the process of aligning an image that is tilted or skewed to make it appear more visually appealing and easier to work with. Feb 20, 2017 · Text skew correction with OpenCV and Python The remainder of this blog post will demonstrate how to deskew text using basic image processing operations with Python and OpenCV. To determine the skew angle, we compare the maximum difference between peaks and using this skew angle, rotate the image to correct the skew. Oblique projections will commonly pass both through lines of text, and spaces between lines, the variance in the number of pixels hit by the individual rays will thus be smaller than in the parallel case. in general, there has always been an angle displacement occurs from the original axis of the text image. Notice the uniform nature of the distribution After detecting the skew, it is necessary to correct for it. vrvjz fsc jpapovx zzwqnrl fllkg mysppb shwtx gwz zof ebhheea
